  • A multi-radix approach to asynchronous division 

    Cornetta, Gianluca; Cortadella, Jordi (Institute of Electrical and Electronics Engineers (IEEE), 2001)
    Conference report
    Open Access
    The speed of high-radix digit-recurrence dividers is mainly determined by the hardware complexity of the quotient-digit selection function. In this paper we present a scheme that combines the area efficiency of bundled ...

  • Evaluating A+B=K conditions in constant time 

    Cortadella, Jordi; Llaberia Griñó, José M. (Institute of Electrical and Electronics Engineers (IEEE), 1988)
    Conference report
    Open Access
    The authors consider a type of condition that can be evaluated without requiring a complete ALU (arithmetic logic unit) operation. The circuit that is presented detects the condition A+B=K (n-bit numbers) in constant time, ...
  • Infinite families of 3-numerical semigroups with arithmetic-like links 

    Aguiló-Gost, Francesc (Iniciativa Digital Politècnica, 2011)
    Conference report
    Open Access
    Let S = a, b,N be a numerical semigroup generated by a, b,N ∈ N with 1 < a < b < N and gcd(a, b,N) = 1. The conductor of S, denoted by c(S) or c(a, b,N), is the minimum element of S such that c(S) + m ∈ S for all m ∈ N ...

    Corella Pérez, Sandra (Universitat Politècnica de Catalunya, 2015-07-01)
    Bachelor thesis
    Open Access
    Construcció i estudi de mètodes iteratius d'un i dos passos per a la resolució d'equacions no lineals amb l'operador diferències dividides. Estudi d'ordres i radis de convergència, comparativa de llibreries de multiprecisió ...
  • On secret sharing with nonlinear product reconstruction 

    Cascudo, Ignacio; Cramer, Ronald; Mirandola, Diego; Padró Laimon, Carles; Xing, Chaoping (2015-06-24)
    Article
    Open Access
    Multiplicative linear secret sharing is a fundamental notion in the area of secure multi- party computation (MPC) and, since recently, in the area of two-party cryptography as well. In a nutshell, this notion guarantees ...
  • Rainbow-free 3-colorings in abelian groups 

    Montejano, Amanda; Serra Albó, Oriol (2009-07-27)
    Article
    Open Access
    A 3–coloring of an abelian group G is rainbow–free if there is no 3–term arithmetic progression with its members having pairwise distinct colors. We describe the structure of rainbow–free colorings of abelian groups. ...
  • The automorphism group of the non-split Cartan modular curve of level 11 

    Dose, Valerio; Fernández González, Julio; González Rovira, Josep; Schoof, Rene (2014-11-01)
    Article
    Restricted access - publisher's policy
    We derive equations for the modular curve X-ns(11) associated to a non-split Cartan subgroup of GL(2)(F-11). This allows us to compute the automorphism group of the curve and show that it is isomorphic to Klein's four ...
  • The curious arithmetic of optical vortices 

    Molina Terriza, Gabriel; Recolons Martos, Jaume; Torner Sabata, Lluís (Optical Society of America, 2000-08-15)
    Article
    Open Access
    The superposition of noncoaxial light beams containing screw wave-front dislocations is shown to create light patterns with a richer vortex content than that given by the arithmetic of the topological charges of the ...
